The time of manufacture and the hours-of-use counter aren't cleared with a normal PRAM zap. They can be cleared only by a "deep zap", which can be administered by tools like TechTool, for last resort troubleshooting purposes (TechTool restores the manufacturing date and hours-of-use counter after a deep zap, if so desired). ,xtG .tsooJ -- Joost van de Griek http://www.jvdg.net/ -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
